CENTFHF'UGAL CREAM SEFARATOR.

SPECIFICATION forming part of Letters Patent No. 793,759, da ed July 4t, 1905. Application filed March 17 1905. Serial No. 250,557.

In all IIf/tU/Ib it may concern.-

Be it known that I, SEVERIN C. ANKER- IIourn, a citizen of the United titates, residing at Riverside, in the county of (,look and State of Illinois, have invented certain new and useful Improvements in Centrifugal I)roan1-Se1 arators, of which the following is a specil'icatioi'i, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to centrifugal creamseparators; and it consists in an improved form of cover for the bowl, wherein the crean'i-outlet placed near the lower end'of the neck and below the annular channel into which the skim-milk is discharged, it being found in the operation of this class of ma chines having the cream-outlet near the top of the neck and above the skim-milk outlets that there was a frequent partial clogging of Imtter-fat in the contracted portion of the neck above the milk-outlet, and part of my invention is designed to remove that evil.

It further consists in providing an improved feed device for (.lelivering the full milk to the division contrivances, which consists in a se ries of vertically-arranged channels opening inward and another seriesof channels opening outward and separated from the inwardlyopening channels by partitions extending upward between the side walls of the channels and having openings at their tops COIIIIDI'HII' eating with the inner and outer channels.

It further consists in an improved device for retaining the disks or conical liners in position when removed from the bowl for the purpose of being cleaned; and the objects of my iniprovemei'its are to provide feeding and separating devices that will be both eIiicient in operation and easily placed in or removed from the bowl. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure I is a sectional elevation of a separator bowl complete having my improvements embodied therein. Fig. 2 is a sectional detail of a part of the disk-retaining device. Fig. 3 is a plan view, partly in section, of the disk-retaining device and feed device. Fig.

4 is a sectional elevation of the disk-retaining device. Fig. 5 is a detail of a part of the disk-retaining device, and Fig. 6 is a detail of part of the feed device.

Similar numerals refer to similar parts throughout the several views.

The drivii'ig-shaft 7 is secured to the bottom 8 of the bowl 9, having the conical cover 10 provided with the contracted upwardlyextending neck portion II, having the inter nal skim-milk-receiving annular channel 112 into which a series of skim-milk tubes 13, e. tending outward and downward and connnn nicating with the space near the inner surface of the bowl at its upper end, deliver the skimmilk thereto.

14 is a skim-milk outlet through the upper wall of the channel at the top of the neck, and 15 is a screw that serves to regulate the size of the opening.

The cream-outlet 16 is located at the lower end of the neck below the milk-receiving channel and is in position to receive and deliver the cream at a line near the upper surface of the division contrivances, avoiding the danger of clogging of the upper part of the neck with butter-fat. A tubular feedthroat I7 ex" tends downward through the neck, and its outer surface forms the inner wall of the channel 12. At the bottom of the bowl is a receiving-chamber 18, having an opening in its bottom that [its over a boss 19 on the bottom of the bowl for the purpose of centering the chamber therewith. An axial opening 19' is made in the top of the chamber, and a series of channeled bars 2.0, concentrically arranged around the opening at a distance from the axis of the bowl, connects the chamber 18 with the throat 17. The bars are preferably made wider in a radial than in a circumferential direction and have deep inner radial channels 21, opening inward and communicating with the chamber 18 at their lower ends and inclined inward and upward to meet the throat at their upper ends, and outer shallow radial channels iii), opening outward and separated from the inwardl v-opening channels by means of the partitions 23. Each partition is provided with an opening 24 at its upper end that communicates with both the inner and outer channels. The walls of the outer channels are preferably provided with cream notches or ducts 25, that terminate near the center line of the channels, as shown by full lines in Fig. 6 and dotted lines in Fig. 3. The bowl and feed device are designed to be rotated in the direction of the arrow, as shown in Fig. 3, and the walls of the channels facing the direction of rotation are preferably shortened radially. The body of the bowl surrounding the feed device is occupied by a series of division-plates or conical-shaped liners 26, that are common to this class of machines, and they are usually held in place by means of inwardly-opening notches that embrace the radially-disposed wings of the feed device. In removing the disks from the body of the bowl for any purpose it is desirable that they be retained in the same position relative to the notches that they may be quickly and correctly replaced. It is also desirable that the disks be separated one from another a sulficient distance convenient for cleaning, and the particular means for attaining these objects will now be described.

A conical base 27, conforming in shape with the outer surface of the receivirig-chamber l8 and the angle of the conical liners, surrounds the chamber and suitable distance-ribs 28 are provided to keep their surfaces from contacting. The lower part of the base is in this manner supported at adistance from the bot tom of the bowl, leaving a narrow space 2f) communicating with its interior. A series of inwardlyopening channels 30 are secured to the base and are arranged to embrace the channel-bars 24) upon three sides. A conical hood 31 has secured thereto another series of channels 32, that are arranged to embrace three sides of the first-mentioned channels and to slide thereon. The first-mentioned channels are provided with longitudinallyextending slots 33 through their outer wall, having an enlarged central opening 3 T therein. Near the lower ends of the channels 32 there are secured inwardly-projecting studs 35, provided with heads adapted to pass through the openings 3% when registering therewith and to en gage with opposite sides of the slots 33 when the upper section is moved upor down on the lower section of the device. The two sections being thus connected, they are free to slide one upon the other and the device as a whole be lengthened or shortened. The inwardlyopening notches in the liners 9.6 are arranged to embrace the channels, as shown in Fig. 2, and may be moved up or down thereon, as shown in Fig. 4c. \Yhcn the liners are assembled upon either the upper or lower section of the retaining device. the two sections are coupled together and passed over the feed device, the outer wall of the channelsof the retaining device closing the direct outward opening of the exterior channels of the feed device as the upper section is moved down over the lower, as shown in Fig. 1.

The liners are not removed from the retaining device for the purpose of cleaning. One section of the device is moved longitudinally along the other, and the increased length affords room for the liners to be separated sufficiently for that purpose.

\Vhen the parts are properly assembled, the feed device occupies the central portion of the bowl and the liners, with their retaining device, surround it. The liners are spaced apart by any of the usual means, and the conical hood 31, engaging with the interior conical surface of the cover, presses down upon the topmost one and secures them in position.

The full milk is delivered through the throat, and following the axial opening in the feed device is received by the lower chamber and flowing upward through the inwardly-opening channels and overflowing their sides is delivered to the division contrivances in the outer portion of the bowl. The separated cream ascends along the inner space outside the column of inflowing full milk to the outlet formed in the wall of the neck, while the milk is driven outwardly and ascends through the milk-tubes to the annular channel and thence through the opening provided for its discharge. A portion of themilk, l'lewingnp ward through the inwardly-opening channels and not overflowing their side walls, will pass through the openings in the partitions and reach the exterior channels and, flowing downward, will be distributed to the lowermost liners at the base of the disk-retainer, and a free flow of the separated cream is provided for by the cream notches or ducts through the walls of the channels.
